To all whom. it may concern: longitudinally-opposite sides withregistering Be it known that I, JAMES M. HOLLAND, a perforations 13. Aninverted-V-shaped pin, 5o citizen of the United States, residing atMount having an upper terminal 14 and a lower ter- Pleasant, in thecount-y .of Henry and State minal 15, is mounted removably in the upper5 of Iowa,haveinvented anew and useful Roadand lower openings, and aloop or handle 15 Scraper, of Which the following is a speciiicaisconnected to the upper terminal mentioned.l .mom This pin may bewithdrawn from the stirrup 55 This invention relates to improvements inby the attendant mounted on the platform 5, road-Scrapers, the objectsand advantages of and have its terminals inserted into any of io thesame being hereinafter described, and the pairs of openings 13 of thestirrup.

Thislocking-latch, which posite pairs there is located a platform 5. I haveshown in detail in Fig. 5, comprises a 3 5 The bolster 2 rests upon thefront axle 6, and pair .ofopposite parallel plates or anges 23,

A horizontally-disthe under edges of said plates are at interposedoblong stirrup 12 is secured to the unvals and opposite each otherprovided with der sides of the beams 1,is curved concentric notches 25.

with the king-bolt, and extends laterally at In bearing-lugs formed uponthe invertedeach side of the machine. The stirrup is con- U-shaped hood18, directly in rear of each of 95 structed of angle-iron and isprovided at its the bails 2/1 of the locking-latch, bell-crank levers 26are pivoted, there being in this instance two bails and two levers. Thelower branches or members of the levers are convexed to constitute cams27, and above each of said members there extends from the verticalportions-of the levers a locking-lug 28. The upper ends of thebell-cranks are connected by a bar 29, pivoted, as at 30, to the saidbell-crank. To the rear end of the hood there is pivoted, as at 3l, asimple lever 32, and the same is connected by a wire or rod 33 with therear end of the connecting-rod 29. By this construction it will be seenthat by a rearward movement upon the part of the lever 32, which may beaccomplished by the hand of the operator, the aforesaid bell-cranks maybe swung to the rear, their cam-faces 27 rising under the bails 24, andthus elevating the locking-latch, so that the lower edges ot' its sideplates or fianges 23 are elevated above the iianges of theinverted-U-shaped hood 18, or, rather, the longitudinal slots 19, formedby the hood and barA l1. Of course such elevating of the latch will bepermitted by the withdrawal of the locking-lugs 28 from over the bails24. By swinging the lever 32 to the front the movement is reversed, thelocking-latch being lowered,and the lugs 28 swung over upon and lock thebails and locking-latch in a lowered or depressed position.

34 designates the transversely curved scraper-blade, to the rear side ofwhich at its center brackets 35 are secured. A pin or bolt 36 is securedin the upper bracket, as best shown in Fig. 4. A V-shaped brace 37 hasits front branch pivoted upon the bolt 36, its lower angular end reducedand pivoted, as at 38, to the lower bracket 35, and its rear end boltedby one of the bolts 17 to the under side ofthe reach-bar.` The pin orbolt 36 also passes through the rear bar 1l, so that the bracket isrigid and the scraper-blade capable of swinging laterally upon thepivots 36 and 38. Vertically-opposite pairs of brackets 39 are alsosecured to the rear side of the scraper -blade near the ends thereof,and from each of these brackets extend rearwardly a metal strap 40, theforward ends of which are pivoted by bolts 4l to the brackets and therear ends of which are converged, meet, and are pivotally connected tothemselves and to the ends of a horizontal connecting-bar 42 by means ofpivoting-bolts 43..

making the ends of the beams L-shaped, as indicated at 48. TheseL-shaped ends or fingers engage with the slots 19, the horizontalportions of the ends riding in the slots, and the fingers or bent endsof the beams riding against the inner faces of the flanges of the hood18. By raising the locking-latch in the manner heretofore described-thatis, through the medium of the lever 32-and swinging the scraper to theright or left, thus changing the relative positions of the beams 45 andreleasing the latch, the notches of the latter will take over andreceive the front extremities of the beams, and thus lock the beamsagainst movement, so that the scraper after having been moved to anydesired angle by suitable mechanism may be locked and retained againstany undesired displacement. Various mechanisms may be employed foroperating the scraper, but I prefer the mechanism hereinafter describedfor this purpose.

In Figs. 1 and 7, 49 designates a pairof side cutters or wings, whichare provided with L-shaped metal straps 50, secured to their faces, saidstraps having adjustingholes 51, by means of which they may be securedthrough the medium of bolts to the opposite ends of the scraper-blade.These wings or side Scrapers 49 are secured to the opposite ends of theblade or scraper when the same is set at a right angle to the line ofdraft of the machine, or substantially so, and said machine is employedfor shoveling or drawing dirt from one point to another. By theemployment of these beams or side scrapers the capacity of thescraping-blade is increased, as the dirt cannot run olf the sides orends, as it would were such wings or blades not present.

In standards 52, supported on the rear ends of the beams 1, there arejournaled two transverse shafts 53, and the said shafts have mountedrigidly thereon near their extremities a pair of beveled pinions 54, andbetween the saine a pair of hand-wheels 55. Upon the beams or sills l,in front of the shafts 53, bearings 56 are located, and in the same apair of opposite longitudinal shafts 57 are journaled. These shafts areeach provided at their rear ends with a beveled gear 58, meshing with apinion 54, and at their front ends with small beveled pinions59. Inarched standards 60, located in front of the pinions 59, shorttransverse shafts 6l are journaled, and each of these shafts is providedat its outer end with a crank or rockarm 62. Within the standard andbetween the beams or sills l beveled gears 63 `are mounted on the shafts6l, and the same are engaged and driven by the beveled pinions 59 of theshafts 57.

The crank or rock arms 62 are provided at their ends with U-shaped yokes64, said yokes being provided at their rear sides with pins 65, looselyjournaled in the crank or IOO IIC

' the brake 70 to the foot-lever.

Ass

rock arms, and pivoted in each yoke by trunnions 66 is a sleeve 67,provided at its outer side with loops or keepers 68. The loops orkeepers of each sleeve receive the upper end of a scraper-bladesuspension rod or standard 69, the same being perforated at intervalsfor the reception of adj usting-bolts 69, (best shown in Fig. 2,) andpassing through the keepers 68 of the sleeve 67.

Spring brake-shoes 70 are secured to each of the standards 3 andnormally press against the peripheries of the hand-wheels 55. Below eachbrake-shoe there is pivoted to the platform 5, as at 71, a foot-lever72, and a connecting-rod 73 leads from the free end of By this it willbe seen that the hand-wheels 55 are constantly locked against rotationand may be released at any moment for such rotation by means of the footof the operator exerting downward pressure upon the foot-levers.

In a cross-bar 74 there is journaled a vertical shaft 75, and the sameis provided at its upper end with a hand-wheel 76, by which the shaftmay be rotated. A bar 77 is provided at its rear end with an eye 78,which loosely receives the shaft 7 5, and at its front end has looselyjournaled thereon a grooved roller 79, mounted upon a transverse track80, located between the two inner sills or beams 1 of the frame. Betweenits ends the bar 77 is provided with an elongated eye 81, and in this isjournaled the short transverse shaft 82 of a grooved pulley 83. A chain84 has one end connected to the shaft 7 5, and its front end passed overthe pulley 83, below which it depends, and is connected by links 85 tothe inverted-U-shaped hood 18, heretofore described.

Upon the front edge of the cross-bar 74 a vertical standard 86 ismounted, the upper end of said standard extending inwardly, and beingperforated to receive a Vertical detent or bolt 87, the lower end ofwhich is, through the medium of its coiled spring 88, that encircles thesame, normally pressed into engagement with the indentations or teethformed in the periphery of a ratchet-wheel 89, which is mounted xedlyupon the shaft 75. From the rear edge of the aforesaid crossbar 74 risesa short standard 90, and the same has fnlcrumed, as at 91, upon itsupper end, a lever 92. This lever has its front end pivoted, as at 93,to the upper end of the bolt 87, and its rear end is connected by a rod94 to the lower front end of a foot-lever 95, fulcrumed, as at 96, uponthe platform 5, as best shown in Figs. l and 2.

^ By operating the wheel 76 it will be seen that the chain 84 may bewound upon the shaft 75. Previous to such operation, however, the twohand-wheels are rotated until, through the medium of their connections,the gears 63 and their shafts 61 are rotated sufiiciently to bring therock-arms 62 to their highest or most ,elevated position-namely,

vertical. Such movements of the rock-arms through the medium of thestandards 69 elevates the scraper-blade and the mechanism employed forsupporting it-that is, the bar 11 and its hood 18, the ends of the bar11 moving up the vertical clevis or bail 10 and the terminal 15 of theinVerted-V-shaped adjusting-pin. formed in the chain is taken up byrotating the shaft and winding the chain thereon. When operating thisshaft for the purpose of taking up the chain, the foot-lever 95 isdepressed, soas to raise the bolt from engagement with the ratchet, andthus liberate the shaft. When thus suspended, by operating thehand-wheels 55 in opposite directions the scraper may be swung from sideto side upon its pivot-that is, in a vertical manner-so as to raise orlower either end thereof. By manipulating the inverted-V- shaped pin therear end of the bar 11 may be adjusted in any of the perforations 13 ofthe It is at this time that the slack thus stirrnp, and thus disposed atan angle to the line of draft and give to the scraper-blade a properangle. It will thus be seen that the raising and lowering of the end ofthe blade may be accomplished from the platform 5 and with greatfacility, requiring but very little power or exertion and simply therotations of the wheels 55 and 76.
